Circular economy in manufacturing: strategies for circular, resource-efficient production

How circular manufacturing differs from a linear model

In a traditional linear model, manufacturing follows a simple sequence: extract materials, make products, use them, then dispose of them as waste. This “take-make-waste” logic has driven industrial growth for years, but it locks in resource risk, rising costs and environmental impact. The Circularity Gap Report 2026 puts a price on it: an estimated €25.4 trillion in value is lost every year to linear practices, against global GDP of €82.6 trillion. Meanwhile, the 2025 edition found that only 6.9% of materials entering the global economy are secondary materials, down from 7.2% in the 2024 edition.

Circular manufacturing replaces this with a system where products, components and materials stay in use for as long as possible, at their highest possible value. Instead of treating waste as inevitable, manufacturers start to design and operate so resources circulate in closed or semi-closed loops. The result is production that protects margins as well as protecting the planet.

When we talk about the circular economy in manufacturing, we typically anchor it around three circular economy principles used by the Ellen MacArthur Foundation:

1. Eliminate waste and pollution
   Waste is treated as a design and process failure, not an unavoidable by-product. Product and process design aim to reduce material use, avoid hazardous substances, and enable reuse and recycling from the outset.
2. Keep products and materials in use
   Products are designed for durability, repair, refurbishment and remanufacturing. Components and materials are recovered and cycled back into manufacturing or other productive uses.
3. Regenerate natural systems
   Where bio-based materials are used, manufacturing models support regeneration rather than degradation, for example through responsible sourcing of sustainable materials, renewable energy, and restorative land-use practices in supply chains.

Industrial symbiosis is an important part of this shift. It describes collaboration between different manufacturers or industrial sites so that one organisation’s by-products, excess heat or secondary materials become another’s inputs. Instead of paying to dispose of by-products, businesses treat them as valuable resources, strengthening both circularity and competitiveness.

Why resource value matters across the product lifecycle

In circular manufacturing, every stage of the product lifecycle is seen through a resource-value lens. Rather than focusing only on unit cost at the factory gate, you consider:

• How efficiently you use materials and energy in production.
• How long products remain in use, and how often they are repaired instead of replaced.
• How effectively you recover components and materials at end of use.
• How much value you can recapture via reuse, refurbishment, remanufacturing and recycling.

Europe shows how much headroom remains. In 2024, 12.2% of materials used in the EU came from recycled sources, the highest figure on record but still well short of the EU’s goal to double its circular material use rate by 2030.

This lifecycle perspective changes decision-making. A component that is slightly more expensive but lasts longer, is easier to repair, and can be remanufactured, may deliver a lower total cost of ownership and a more sustainable profile than a cheaper, disposable alternative.

Common questions at this stage include:

• Can we design this product so it will be easier to disassemble and separate materials at end of life?
• Can we standardise parts and fasteners so refurbishment or remanufacturing becomes more straightforward?
• What recycling or reuse options exist for our critical materials today, and where are the gaps?
• How can we work with customers and logistics partners to get products back when they are no longer in use?

When you treat “waste” as a misplaced resource, you start unlocking a broader set of circular economy opportunities across key business areas like design, sourcing, production, logistics and after-sales models.

Where circularity fits across manufacturing operations

Design products for durability, repair and disassembly

Circular manufacturing starts at the drawing board. According to the European Commission, more than 80% of a product’s environmental impact is determined at the design stage, so design for repairability, durability and disassembly is fundamental. In the EU, the Ecodesign for Sustainable Products Regulation (ESPR) is turning this into law, with powers to set product rules on durability, repairability and recycled content. Our guide to circular design principles explores this in more depth.

Key design strategies for sustainable products include:

• Durability and robustness: Specify materials and components that can withstand expected loads, usage patterns and environments, and test for extended lifetimes. Modular architectures allow critical parts to be upgraded without scrapping the whole product.
• Repairability: Use standard fasteners instead of glues, welds or permanent bonds where possible. Ensure there is physical access to parts likely to fail. Provide service manuals, diagnostic tools and spare parts so that trained technicians, or in some cases end users, can repair products.
• Disassembly and material separation: Design so that products can be taken apart with minimal steps and tools, and so that materials can be separated into clean streams for recycling. Avoid unnecessary material mixing or problematic coatings that reduce recycling potential.
• Material choice and labelling: Where you use plastics, alloys or composites, choose grades that have viable recycling markets and clearly label them. Avoid substances that complicate recycling or create compliance risks.

Design for longevity and repair aligns environmental and commercial goals. Manufacturers can build service revenue streams around maintenance, upgrades and refurbishment instead of relying solely on new product sales, turning good design into commercial advantage.

Manage materials and resources more efficiently

Once design is in place, the next lever is operational: reducing waste and improving resource efficiency in production.

Approaches include:

• Process optimisation and lean manufacturing: Techniques such as lean, Six Sigma and digital process control help minimise scrap, rework and over-processing. This directly reduces material and energy use per unit produced.
• Industrial symbiosis and recycling partnerships: By understanding the composition and volumes of your by-products, you can identify reuse or recycling options inside or beyond your own facilities. For example, heat networks can capture waste heat from one plant to serve another, and off-spec materials can be downcycled into other industrial products rather than disposed of.
• Closed-loop recycling in manufacturing: Closed-loop recycling refers to systems where recovered materials are processed and returned to the same or similar products. In manufacturing, this could mean capturing production scrap, cleaning and regrinding it, then feeding it back into your own process in controlled proportions. It can also involve working with recyclers to turn post-consumer returned products into secondary raw materials that re-enter your supply chain. Effective material management and sortation make this possible at scale.
• Material and energy monitoring: Real-time data on material yields, water use, energy intensity and waste outputs highlights where changes will have the biggest impact. Over time, you can benchmark plants, lines or suppliers on circularity-relevant performance indicators.

By treating every tonne of material and every kilowatt-hour as a valuable resource, manufacturers reduce cost while creating more sustainable and resilient operations.

Keep products and components in use through repair and remanufacturing

A central objective of the circular economy is to keep products and components in use for as long as practical. Repair, refurbishment and remanufacturing are separate but paired strategies:

• Repair: restores a faulty product to working order, typically at or near the point of use.
• Refurbishment: typically involves inspecting, cleaning and replacing limited parts to return a used product to a functional, often “good enough” condition. Cosmetic issues may remain.
• Remanufacturing: a more rigorous industrial process where a used product is completely disassembled, critical components are replaced or reprocessed to “as new” specification, and the product is reassembled and tested to original performance standards.

The environmental case is strong. Research from the UN’s International Resource Panel found that remanufacturing can cut the new material needed by 80 to 98%, and that value-retention processes like these could reduce greenhouse gas emissions by 79 to 99% in some sectors.

The difference between refurbishment and remanufacturing matters for quality assurance, compliance and how you position products in the market. Remanufactured goods usually come with warranties comparable to new products and may be sold as equivalent performance at a lower price.

To support these models, manufacturers can:

• Design products and supply chains with standardised components that are easy to remove and reuse.
• Establish remanufacturing facilities or partnerships in key regions.
• Use reverse logistics programmes to collect products at the end of initial use.
• Create clear channels for spare parts, service information and upgrade paths.

These practices not only improve circularity but also create new revenue streams, such as certified pre-owned products, extended warranties and maintenance contracts, that can be more predictable than one-off product sales.

Connect production with resource recovery

Use returns and reverse logistics to recover products

Reverse logistics is the backbone of circular manufacturing. It covers the flows needed to bring products, components and materials back from customers, distributors or collection points into your own organisation or partners’ facilities for assessment and processing.

For manufacturers, effective reverse logistics solutions support:

• Warranty and non-warranty repairs.
• Refurbishment and remanufacturing at scale.
• Recovery of high-value materials that cannot be easily sourced elsewhere.
• Compliance with producer responsibility and take-back regulations.

Building reverse logistics for product returns typically involves:

• Clear processes for customers to return products at end of use, via mail-back, collection points, service centres or retailer take-back schemes.
• Sorting and triage capabilities so items are quickly directed to reuse, repair, refurbishment, remanufacturing or recycling.
• Integration between logistics providers, service teams and inventory systems so you treat returned products as assets, not as waste.

When manufacturers design logistics, IT systems and service contracts together, they can significantly increase the proportion of returns that are reused or remanufactured rather than discarded. A joined-up approach to returns management is what makes this sustainable over the long term.

Build closed-loop supply chains for materials and components

A closed-loop supply chain aims to circulate materials and components continuously, linking production and use with recovery and recycling. This is where the circular economy moves beyond a single factory and into the wider circular economy supply chain.

In manufacturing, this may involve:

• Setting up return channels for specific components (e.g. batteries, motors, cartridges) that carry high material value or pose environmental risks if discarded.
• Working with recyclers and material processors to convert end-of-use products back into secondary raw materials that can be re-specified in new products.
• Sharing data on material composition so downstream recyclers can process products more effectively, and you can trust the quality of secondary materials coming back.

Closed loops can be fully internal, such as reusing your own process scrap, or involve multiple organisations across the industry through industrial symbiosis. In both cases, traceability, quality control and clear commercial arrangements are critical.

Closed-loop recycling vs open-loop recycling

Closed-loop recycling returns a material to the same or a similar product at the same quality. Open-loop recycling turns it into a different, usually lower-value product, which is often called downcycling. A PET drinks bottle recycled into a new PET bottle is closed-loop recycling. The same bottle turned into polyester fleece or strapping is open-loop recycling.

Both have a role. Open-loop recycling still keeps material out of landfill, but each pass usually lowers quality, and the material eventually leaves the system. Closed-loop recycling keeps material at its highest value, which is why manufacturers with control over their products and return flows increasingly design for it.

Closed-loop recycling examples in manufacturing

Apple: recovering critical materials from iPhone and other devices

Apple’s disassembly robot, Daisy, can take apart 36 iPhone models and process 200 devices an hour, separating components so materials such as cobalt can be recovered. Apple now uses 100% recycled cobalt in the batteries it designs, and has used recycled aluminium since the iPhone 6s in 2016.

Apple also runs Advanced Recovery Centres, where technicians are guided through device disassembly so that more materials are recovered. The Apple example shows how design for disassembly and take-back make closed-loop recovery of critical materials possible at scale, with recovered material feeding back into new Apple devices.

Coca-Cola: bottle-to-bottle PET

In 2021, Coca-Cola Great Britain moved all of its plastic bottles of 500ml or less to 100% recycled PET, taking its total saving of virgin plastic to around 29,000 tonnes a year. Bottle-to-bottle recycling is one of the clearest examples of a closed loop: food-grade PET bottles are collected, cleaned, reprocessed and made into new bottles. The system depends on getting enough bottles back, which is why collection and deposit return schemes matter so much to drinks producers. A deposit return scheme for drinks containers is scheduled to begin in England, Scotland, Wales and Northern Ireland in October 2027.

Aquafil: ECONYL nylon from carpet tiles and fishing nets

Italian manufacturer Aquafil’s ECONYL Regeneration System collects nylon waste such as fishing nets, fabric scraps and carpet flooring, and regenerates it into nylon with the same qualities as new. The yarn is used in the manufacture of carpet tiles and other flooring, as well as fashion and automotive products, so old carpet tiles can become new carpet tiles. For flooring manufacturers, modular flooring such as carpet tiles that can be lifted, returned and regenerated through Aquafil’s ECONYL system is a practical model for closing the loop.

UK packaging closed loop recycling under EPR

UK packaging EPR now recognises closed-loop recycling directly. Under government guidance on closed loop packaging waste, large producers can offset the weight of closed loop packaging they collect and recycle against the weight of household packaging they supply. To qualify, the packaging must:

• Be food-grade plastic household packaging, such as PET ready-meal trays.
• Be collected by or on behalf of the producer, without being mixed with other waste.
• Be sent to a single accredited reprocessor or exporter, in the UK or overseas, and recycled back into food-grade plastic material.
• Have been supplied as filled packaging on or after 1 January 2024.

Producers must hold evidence that every condition has been met and pay to submit closed-loop data. From 2027 onwards, producers opt in through their annual large producer registration, deciding by 1^st October each year whether to report closed-loop data for the following year.

Product-as-a-service models

Product-as-a-Service (PaaS) models shift the basis of value from selling units to selling outcomes or performance. They are among the most effective circular economy business models for manufacturers, because they reward products that last. Instead of selling a machine outright, you might offer:

• Capacity (e.g. hours of operation).
• Output (e.g. number of parts produced).
• Function (e.g. compressed air as a service, lighting as a service).

Product-as-a-Service models usually fall into three types:

• Product-oriented services: you still sell the product, but bundle in maintenance, repair, upgrades and take-back at the end of use.
• Use-oriented services: the customer leases, rents or shares the product, and you keep ownership throughout.
• Result-oriented services: the customer pays only for the outcome, such as parts produced or uptime delivered, and you decide how best to deliver it.

Because you retain ownership of the equipment, you have a direct incentive to:

• Design for durability, upgradability and repair.
• Monitor use and optimise maintenance through digital tools.
• Take back products at the end of contracts for refurbishment or remanufacturing.

This naturally supports circular manufacturing, as you control the full resource cycle: design, manufacture, deployment, maintenance, recovery and reuse. For customers, PaaS turns large capital purchases into predictable operating costs and makes the sustainable choice the easier one.

PaaS is not without challenges. It changes how you recognise revenue, holds more assets on your balance sheet, and depends on reliable data about how products are used. Many manufacturers start with a pilot on a single product line or customer segment before scaling.

Take-back schemes and producer responsibility

Even where full PaaS is not yet viable, take-back schemes can help you recover products and materials. These may be:

• Voluntary programmes to encourage customers to return used products for responsible recycling or reuse, such as circular take-back and recycling schemes.
• Mandatory schemes under extended producer responsibility (EPR) regulations, where producers must finance or manage collection and recycling of certain product categories.

In both cases, combining take-back with robust reverse logistics and clear customer communication creates a practical pathway to higher circularity and a more sustainable product portfolio.
